' INVENTOR. B ymwz RDupZer W7 MAW ATTORNEY Patented Dec. 30, 1947UNITED,- STATES A N 3 Claims.

This invention relates to-illuminated globes such, for example, asglobes having a source of light on the inside and the outside covered bytranslucent terrestrial or celestial maps, and an object is to produce anew and improved illuminated globe structure in which the globe is inthe form of two hemispherical shells, the globe being supported byeither a full meridian ring or semi-meridian ring by simple andefiicient means.

Other objects and advantages will hereinafter appear and for purposes ofillustration but not of limitation, an embodiment of the invention isshown in the accompanying drawings in which Figure 1 is a side elevationof the illuminated globe structure;

Figure 2 is an enlarged vertical sectional elevation of the globe andmeridian ring; and

Figure 3 is an enlarged transverse sectional view substantially on theline 33 of Figure 2.

The illustrated embodiment of the invention comprises a globe in theform of two hemispherical shells l and H. The shells l0 and II arepreferably of glass but may be of any suitable transparent ortranslucent material. In the region of the north pole the shell It isformed with an inwardly extending post l2 having an outwardly openingsocket I 3 which may be of any desired shape. Fitting within the socketI3 is a block I4 which may be of metal, and adhesive such as glue may beemployed for fastening or cementing the block within the socket.Integral with the block I 4 and projecting outwardly therefrom is acylindrical post l5 which extends into an aperture or socket formed in afull meridian ring Hi. It will be observed that the outer side of theblock I is flush with and conforms to the adjacent peripheral surface ofthe shell In.

In order to insure that the block will be held securely in position, itis provided with a screwthreaded shank I1 which extends through anaperture in the bottom wall of the socket l3. A nut l8 engages the shankI! to hold the block securely in place.

The two shells l0 and II are secured together at their abutting edges bya strip I9 of trans parent adhesive tape commercially known as Scotchtape. Obviously the light rays from the inside of the globe pass throughthe Scotch tape and when the same is covered by a map or some decorativedesign, the same will be obscured from view and will not be noticeable.Tape of this character possesses substantial strength sufficient to holdthe two shells in the desired relation.

At the opposite end .or south pole of the globe is a combined lampbracket and. globe. -supporti which has a block 20 of polygonal crosssection.

The block 20 fits a notch 2| on the inner side of the meridian ring l6and this notch is open at opposite sides so that the block may beslipped laterally in one direction or the other as desired. A screw 22extends through the opening in the meridian ring and threadedly engagesthe block 20 thereby to hold the same in the desired position. Mountedon the block 20 is a ring 23 which extends into and fits an openingformed in the shell II. On the lower end of the ring 23 is an outwardlyextending flange cap 24 which engages the outer side of the shell H inthe region adjacent to the edge of the'hole.

Suitably secured to the ring 23 and projecting inwardly therefrom insideof the globe are fingers 25 which support a lamp socket 26 carrying anelongated lamp bulb 21. The wiring 28 for the lamp passes through anopening in the side of the block 20 and thence upwardly between thefingers 25 to the socket 26.

From the above description it will be manifest that I have produced anexceedingly simple and practical globe assembly enabling the use ofhemispherical shells which can be more readily produced than theone-piece globe. The shells can be readily molded and the attaching ormounting parts quickly and easily applied. When it is desired to detachthe globe from the ring IE, it is merely necessary to loosen the screw22 and then bodily shift the block 20 and its adjacent parts laterallyclear of the notch 2!. This rocking action is possible due to themounting of the post IS in its aperture or socket. Thereafter, the lampbulb 21 can be readily replaced if nec essary. The structure is suchthat it can be simply and inexpensively produced and the assemblyproblems reduced to a minimum.

It is to be understood that numerous changes in details of construction,arrangement and operation may be efiected without departing from thespirit of the invention especially as defined in the appended claims.

What I claim is:

1. Illuminated globe structure comprising a globe in the form of a pairof hemispherical shells, means for adhesively joining said shells, oneshell having an inwardly extending socket, a block within said sockethaving an outwardly projecting post, means for securing said blockwithin said socket, an arcuate mounting for said globe having a socketedportion to'receive said post, said arcuate mounting having a notcharranged diametrically opposite said socketed portlon, opposite sides ofsaid notch being open, a combined lamp socket and globe support mountedin said notch, and a fastener for detachably securing said support tosaid mounting, whereby upon loosening said fastener, the support may bebodily moved from said arcuate mounting and then the post slipped out ofits socketed portion.

2. Illuminated globe structure as claimed in claim 1, wherein the, meansfor. securingtheblock in the socket comprises a threadecli'shankdepending from said block through an aperture in the bottom of saidsocket, and a nut on the inside. of said shell engaging said shank.

3. Illuminated globe structure as: claimed". im'

claim 1, in which said combined lamp socket, and. globe supportcomprises a polygonarblock fitting v said notch for preventingturningofrthexhlock; a flanged ring on said block with the flangethere-., of engaging the outer side of the respective shell and the ringextendinginto an opening in the shell; a lamp :socket on said ring. andprojecting inside of the globe, and a screw in said arcuate mounting inscrew-threaded engagement with said polygonal block.
